Is it possible to find all images below 300dpi in a book document?

Report · Oct 25, 2018

Hi there, I'm hoping this is a quick question. I've had a look on google but to no avail.

This script run in open document only to search and plug images below 300dpi.

Is it possible to run this script in Book File?

var lowResList = new Array;

 oneGraphic = app.activeDocument.allGraphics[aGraphic];

Below is a sample demonstration script written for AppleScript that does what you are looking for. It produces a list of the names of graphics where effective PPI is less than 299 or greater than 301 for both the x and y parameters. This can give you some ideas for your ExtendScript.

tell application "Adobe InDesign CC 2018"

set bookCount to count of books

if bookCount = 0 then

set fileRef to choose file

set bookRef to open bookFile

else

set bookRef to book 1

end if

set badList to {}

set bookFiles to book contents of bookRef

with timeout of 500 seconds

repeat with i from 1 to length of bookFiles

set thisDoc to item i of bookFiles

set docStatus to status of thisDoc

if docStatus is not "document is open" then

set docPath to full name of thisDoc

set docRef to open file docPath

else

set docName to name of thisDoc

set docRef to document docName

end if

tell docRef

set graphicList to all graphics

end tell

repeat with j from 1 to length of graphicList

set thisGraphic to item j of graphicList

set thisPPi to effective ppi of thisGraphic

set thisTest to 0

if item 1 of thisPPi < 299 or item 2 of thisPPi > 301 then

set thisTest to thisTest + 1

end if

if item 2 of thisPPi < 209 or item 2 of thisPPi > 301 then

set thisTest to thisTest + 1

end if

if thisTest > 0 then

set end of badList to name of item link of thisGraphic

end if

end repeat

end timeout

end tell

Thanks Hopkins... but I'm not good in translating/reading AppleScript

Hi,

You should be able to get the bookContents and then loop through each entry, making sure it is open in InDesign then run your code on it.

// assuming only one book open.

var myBook = app.books[0];

var allInddFiles = myBook.bookContents;

for ( var i = 0; i < allInddFiles.length; i++)

{

var curDoc = app.open ( allInddFiles.fullName )

// your code here, with changes to cope with using the curDoc variable from above

// close your doc when you are finished

curDoc.close ( SaveOptions.NO);

}

Hope this helps

Hi Malcolm,

I've tried your suggestion but the outcome will open every document create list then closed then open another one create list then close again until the last indesign in a book. Is there a way that it will run first throughout the book then create only one list of images.

Many thanks.

Hi Ryu,

My code doesn't handle the creation of the list document at all, but if you want all images to be listed in one document, create that document before you start the loop and always write to it in the code.

//Something like

var doc = app.documents.add();
for ( var i = 0; i < allInddFiles.length; i++)
{
     var curDoc = app.open ( allInddFiles.fullName )

Sorry, but I already had an AppleScript. Here is the script translated for JavaScript. It's coarse, I know but pretty much line for line. That way you can see how easy it is to translate from AppleScript to JavaScript and vice-versa. Script is not thoroughly tested either.

var appRef = app;

var bookCount = appRef.books.count();

if (bookCount == 0) {

var fileRef = File.openDialog("Select inDesign book file");

var bookRef = appRef.open(File(fileRef));

} else {

var bookRef = appRef.books.item(0);

}

var badList = [];

var bookFiles = bookRef.bookContents;

for (var i = 1; i < bookFiles.length; i++) {

var docRef = bookFiles;

var docStatus = docRef.status;

if (docStatus == BookContentStatus.DOCUMENT_IS_OPEN) {

var docName = bookFiles.name;

docRef = appRef.documents.itemByName(docName);

} else {

var docPath = docRef.fullName;

docRef = appRef.open(File(docPath));

}

var graphicList = docRef.allGraphics;

for (var j = 0; j < graphicList.length; j++) {

var thisTest = 0;

var thisGraphic = graphicList;

var thisPpi = thisGraphic.effectivePpi;

if (thisPpi[0]< 299 || thisPpi[0]> 301) {

thisTest += 1;

}

if (thisPpi[1] < 299 || thisPpi[1]> 301) {

thisTest += 1;

}

if (thisTest >0) {

badList.push(thisGraphic.itemLink.name);

}

}//ends repeat j

} //ends repeat i

badList;

Hi Hopkins,

How can I fix this error in your translated code.

Report · Oct 31, 2018

Hi,

for certain types of graphics property effectivePpi is not available.

Like placed AI files or PDFs…

Which is why that part is wrapped in my script in a try...catch block.

Don't need try/catch. Just check the object constructor... let us assume object is named graphic...

if (graphic instanceof Image) {

ppi = graphic.effectivePpi;

} else {

// 'graphic' is not raster (not an 'Image').

}

If you want to skip the code, just download a full working demo of FlightCheck. Drag-and-drop your InDesign file onto it. Look at the main window and see the "images" section. There you can sort by DPI and many other factors.

Try this free script. Select book doc, choose to make a CSV and open in Excel, sort by row PPI and you can see all that fall below whatever value you're after.

Why do you need scripting for this? Why do you not simple use Indesign's preflight to check your book?

Report · Nov 25, 2018

Right.

Preflight will even catch more:

Image data in placed PDFs or AIs, also in placed EPS files.

Is it possible to find all images below 300dpi in a book document?
